We were selectively requiring the tap.rb file in a few places for
performance reasons. The main method we were referencing was the
`Tap.cmd_directories` method which uses `Pathname` and the `TAP_DIRECTORY`
constant internally. `Tap.cmd_directories` is mostly used in the `Commands`
module and that is loaded very early on in the program so it made sense
to move that command to that module. To facilitate that I moved the
`TAP_DIRECTORY` constant to the top-level and renamed it to
`HOMEBREW_TAP_DIRECTORY`. It now lies in the tap_constants.rb file.
A nice bonus of this refactor is that it speeds up loading external
commands since the tap.rb file is no longer required by default in
those cases.
- We discovered that the following syntax in the formula `sqlsmith`
should actually be OK because the `\n` is like whitespace.
```ruby
cmd = %W[
#{bin}/sqlsmith
--threads=4
--timeout=10
]
shell_output(cmd)
```
- I got bored doing them manually.
- Also now more people can help with letters of the alphabet using `brew style --only=FormulaAuditStrict/Text --fix homebrew/core`.
- Previously this only included the formula name.
- But, for example in tests, we have "#{bin}/ansible-test",
not just "#{bin}/ansible". So handle that too.
- I decided to make the error message better by extracting the
binary name from the interpolation, but I'm not sure it was worth it.
```
$ brew audit --strict ansible
ansible
* line 580, col 29: Use `bin/"ansible-test"` instead of `"#{bin}/ansible-test"`
Error: 1 problem in 1 formula detected.
```
- Fixing the test expected output was unbelievably tedious.
- There's been debate about this setting being `false` but in
https://github.com/Homebrew/brew/pull/15136#issuecomment-1500063225
we decided that it was worth using the default since RuboCop behaviour changed
so we'd have had to do some horrible things to keep it as `false` -
https://github.com/Homebrew/brew/pull/15136#issuecomment-1500037278 -
and multiple maintainers specify the `--display-cop-names` option to
`brew style` themselves since it's clearer what's gone wrong.
Recommend the use of `on_macos` and `on_linux` unless we're in
`def install`, `def post_install` or `test do` in which case recommend
`OS.mac?` and `OS.linux?` instead.
